With EASA competence for third country aircraft just around the corner, you would be very unwise to buy one (any VLJ, not just the Eclipse) without ensuring it had EASA type certification.
That's a reasonable precautionary position for a purchase of anything in aviation, but the eloquent "European Union" language used hides the fact that there is no apparent way in which N-reg can be forced to comply with EASA maintenance requirements without EASA accepting FAA airframe and equipment certification, which then makes the subject moot anyway....
EASA cannot have control over foreign aircraft. Under ICAO, all they can do is somehow control those which are long term parked in the EU. If - like many jets - you fly around the place, you will be just another plane flying around..... This, no doubt, is one of many reasons why the DfT kicking-out move was dropped. The regular travellers would escape any parking ban.
I would delay a purchase for a much more pragmatic reason: to make sure the bugs are ironed out. A year or two. Mind you, with 30 months to run, that will take care of itself
I wonder how many of those positions are speculative, and will come up for sale? Lots do, because many position holders run out of money for personal reasons and have to get out.
